Notes:
This playfield layout was also used on Rowamet's 'Heavy Metal' and Taito do Brasil's 1983 'Vortex'. A nearly identical layout was used on Williams' 1982 'Warlok'.
The first game designed and produced with Lane Change was Williams' 1980 'Firepower'.
Blackout was the first pinball game to have computer-controlled general illumination, used for the "BLACKOUT" sequence. This was accomplished using a relay mounted to the backbox floor, called the G.I. Relay, which cut power to all playfield lamps.
Prior to "Blackout", all solid state games from this manufacturer used four bolts to attach the backbox to the cabinet. With "Blackout" and later games, Williams used only two bolts even if the steel was still stamped for four holes.

Notes:
This was the first Widebody game from Stern, although the playfield design was much narrower than the standardWidebody pinballs of the period. The typical playfield of such a game was almost 29" wide. This was only 24".
It was also the first electronic game to use 7-digit score displays. To advertise this, all four score displays simultaneously animate the numbers "1234567" during Game Over mode, followed by flashing "7777777" for three seconds, repeating it again after displaying high scores. There are no added sounds during this animation.

Sound by: Chris Granner, Brian Schmidt
Software by: Bill Pfutzenreuter
Notes:
Williams began using System 11B during the production of "Big Guns", so this game can have either an 11A or 11B system board.
Mark Ritchie stated at the Chicago Expo 2012 that the backbox was made larger by 4 inches because artist Python Anghelo needed more room to build the castle! He also said the King was to be Steve Ritchie, who did the voice for that role.
